The density of the felt is in grams (cm / cm). Density over the General Assembly to lose flexibility, the density is too small will lose wear resistance. Thickness, the thickness of the hair on its function also has a different impact, the use of units can be used in accordance with the appropriate application or use, to avoid the impact of the use.
At present all kinds of blankets points: special goods blankets, general blankets. The difference is the thickness of the hair, the size of the density and color to distinguish the difference; skill request is based on whether the strong, elongated, capillary action to distinguish between the use of units can be selected according to need. Industrial felts are known as industrial felt. General miscellaneous felt: the use of the material is mostly recycled hair, the goods should be used for gaskets, warm, adiabatic, etc., cheap.
